Intervention/exposure
Study type
Interventional
Description of the intervention or exposure
The Acute Pain Service consists of four acute pain consultants (physicians, anaesthetists and chronic pain specialists) who rotate on a weekly basis, typically supported by two pain nurses and a trainee. A standard pain round visit involves pain assessment, chart review, optimisation of pain medication, and patient education. This follows a standardised process, with visit duration individualised to each patient but typically ranging from 10 to 15 minutes.

Once a patient is enrolled, a baseline questionnaire will be filled and randomisation will occur. Participants randomised to a pain team visit with a dog will be introduced to the animal and handler. After this the pain team will take over and complete the visit with the animal still present. The animal and handler may stay a little longer afterwords, depending on patient needs, ward business.

The animal handler will facilitate the participant-animal interaction, positioning the therapy dog in a manner that is comfortable for the participant. The nature of the interaction will be guided by the participant's preferences. The participant may converse about the therapy dog or their own pets, or may choose to pat and directly interact with the dog. The animal will be supervised at all times, in accordance with Te Toka Tumai policy. A therapy dog visit will last approximately 10-20 minutes, consistent with standard practice at our institution.

This is a once only interaction due to the limited availablity of therapy animals.

Participants randomised to pain team review only (standard care at our hospital) will not be visited by a dog at all.

Each participant will answer the same brief questionnaire 20 min after pain team review.

Each questionnaire is expected to take 5min to complete. An additional open ended question regarding the experience of being visited by a dog will be asked of participants randomised to dog visit..

The first 30 participants will be included in the pilot phase of this study. They will be asked additional question about their experience of being approached for the study and asked for feedback.

Both groups will receive standard care which is a pain team review. 50% of patients will aslo receive a pet visit. Recruitment, randomisation and data collection is expected to be completed on the day of recruitment.

Description of the comparator or control
The comparator is a visit by the acute pain service which consists of four consultants (physicians, anaesthetists and chronic pain specialists) who rotate on a weekly basis, typically supported by two pain nurses and a trainee.

A standard pain round visit involves pain assessment, chart review, optimisation of pain medication, and patient education. This follows a standardised process, with visit duration individualised to each patient but typically ranging from 10 to 15 minutes.

The pain specialists will be notified if their patient has agreed to participate. The researcher will facilitate study enrolment, questionnaire administration, data collection without interfering with the delivery of care to that participant and without affecting the work flow of the ward or pain round.

Patients will continue to be visited by a pain specialists as needed during their stay, hence their care will not be altered in any way. As the study enrolment, intervention and data collections completes in a single day, only the pain team visit on that day will be included in the study.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Patients will be randomised to standard care or standard care plus pet therapy on days when pet is available. Enrolled patients will be stratified based on baseline pain score. Stratification will ensure even baseline pain score prior to randomisation.

Randomisation will be done by a statistician and then imported into REDCap. Randomisation allocation will be available as soon as patients have consented, also via REDCap.

Randomisation allocation will be revealed to researcher at a push of a buton via a portable tablet and ony after consent is completed.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Participants will be randomised in a 1:1 allocation ratio to either the intervention group (therapy dog visit) or the control group (no therapy dog visit). Group assignments will be generated after participant enrolment and after entering the baseline pain score. This score will be used to stratify patients prior to randomisation. This will ensure an even distribution of baseline pain severity between the two groups. A cut off score of 6 will be used to divide low vs high pain score patients. A score of less or equal to 6 indicates low-moderate pain whereas a score of 7 and above indicates severe pain

Statistical methods / analysis
Quantitative data analysis will be conducted using R version 4.3.2 or later. We will use a two-way independent ANOVA test to compare mean difference in change scores before and after visiting with the therapy dog (i.e., post-treatment measure minus pre-treatment measure produced a change score for each participant).
